(CNN) - In the crucial swing state of Florida, former Gov. Jeb Bush appears to be the top contender among a crop of potential GOP presidential candidates, while former Secretary of State Hillary Clinton is the overwhelming favorite for Democratic voters, according to a new poll.
The 2-point margin falls well within the poll's sampling error.
Released Friday, the poll shows Bush would top a GOP primary race in the state at 22%, with Florida Sen. Marco Rubio slightly behind at 18%, New Jersey Gov. Chris Christie at 14%, and Sen. Ted Cruz of Texas at 12%.
No other Republican candidate would get more than 9%, with 12% undecided, according to the poll.
On the Democratic side, the primary would be far less divided. Clinton would take 70% of the Democratic vote, with Vice President Joe Biden at a distant second with 9%. Ten percent would be undecided.
"Florida Democrats have eyes for no one but Hillary; seven in 10 back her for the nomination in 2016 and no one else is in double digits," said Peter Brown, assistant director of the Quinnipiac University Polling Institute, in a news release.
"The GOP nomination fight is another story," he added. "It is a forgone conclusion that the 2016 GOP nomination fight in Florida will be very competitive."
In general election matchups, Clinton would be two percentage points ahead of Bush in Florida, but she would have a wider advantage over other potential GOP candidates. If the general election were held today, Clinton would best Christie by a margin of 45%-41%; Rubio, 50%-43%; and Cruz, 52%-36%.
"She is neck-and-neck with former Gov. Jeb Bush and has a narrow lead over Chris Christie," Brown said. "Another Florida favorite son, Sen. Marco Rubio, doesn't fare as well."
If she were to compete against Sen. Rand Paul of Kentucky, she'd topple him, 51%-41%, and she would defeat Rep. Paul Ryan of Wisconsin, 50%-42%, the poll shows.
None of the polled candidates have announced White House bids, but many have fueled speculation with high-profile speaking engagements or flat-out stated that they're considering a run for president.
Bush ginned up more attention around a potential campaign when he touted his conservative credentials this week at a public forum. The former Florida Governor, however, said he hasn't yet made up his mind about running for president.
"There's a time to make a decision," he said Monday. "You shouldn't make it too early, you shouldn't make it too late. There's a time. There's a window. And this is not the time for me. This is the time to show a little self-restraint."
In an interview with Jay Leno on Tuesday on NBC's "The Tonight Show," former President George W. Bush said his brother should "run for president if he wants to. He'd be a great one."
For the survey, Quinnipiac interviewed 1,646 registered voters by telephone from November 12-17. The overall sampling error is plus or minus 2.4 percentage points.
